CHARLES A. FIELDS, OF MINNEAPOLIS, MINNESOTA.

HEAD-Ll GHT SCREEN.

SPECIPICATIONfOfming part of Letters Patent No. 343,632, dated June 151886.

Application filed November 27, 1885. Serial No. 184,047. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES A. FIELDs, a citizen of the United States,and a residentof Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain Improvements in Head-Light Screens, ofwhich the following is a specification.

My invention relates to an adjustable screen, that may be readilyattached to any ordinary locomotive so as to be operated from the cab ofthe locomotive, to wholly or partially shut off the light.

My invention consists, generally,in the construction and combinationhereinafter described, and pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation of a head-light with my device applied thereto, apartial elevation of the boiler and a partial section of the cab beingalso represented. Fig. 2 is a front elevation of the headlight andscreen. Fig. 3 is a detail section of the screen.

A in the drawings represents a head-light, that may be of any preferredstyle or construction. 0 represents a partial elevation of a boiler, tothe front end of which the head-. light is secured by any suitablemeans. B represents a partial section of the cab. These parts may all beof any suitable construction.

To-the front of the casing of the head-light I secure, by any suitablemeans, a bracket, D, within which is journaled a roller, K. This bracketis preferably of substantially the shape shown in the drawings, andprojects in acurved form over the roll K, so as to substantially inclosethe roll, except at the lower side. The bracket projects at one endbeyond the side of the head-light, and upon the roll K in thisprojecting portion is a pulley, H. Asuitable cord, L, is wound partiallyaround the pulley and carried back to the cab;

Upon the roll K is ascreen or curtain, of suitable heavy fabric or othermaterial, as canvas or duck. The lower edge of the screen is providedwith a weight,which is preferably in the form of a heavy roll, Lwhich ispassed through a tube formed in the lower edge of the screen. Theforward edge of the bracket is formed or provided with a projectingledge, D, to which are secured the upper ends of the guide-rods E E. Thelower ends of the rods are secured to a ledge formed on or secured toThese rods the lower part of the head-light. are preferably providedwith suitable fastening-nuts, S S. The roll I is provided with eyes orrings J J, that pass around the guiderods E E. The weight I issufficient to normally hold the curtain or screen down, so that theglass of the head-light is covered and no light can escape therefrom.The cord L is provided with suitable means, as the handle M, and the cabsuitable means, as the ring N and hook O, by which the cord may besocured in position to hold the screen up or allowed to drop to let thescreen down over the light.

It will be seen that with this device the head-light can be covered atany time. This is found to be a great convenience on many occasions, andespecially on the class of engines known as motors, and used onstreetrailways. These engines have a head-light at each end, and it isdesirable to cover the light on the end that is toward the cars.

The screen may also be used for making signals with the light, and willbe found especially desirable for this purpose.

I am aware thatahead-light of a locomotive has been provided with aflexible semi-transparent signal curtain or shade, arranged in front ofthe light inside the glass and wound upon a roller that is actuated by acoiled spring, and having a cord with forked ends that pass over pulleysand are attached to the upper and lower corners of the shade, while theother end may be carried back into the cab, within control of theengineer.

In my construction the curtain is outside the glass,where it is notinjured by the heat from the light, as would be the case were it insidethe glass. When the curtain is rolled up, it is protected from rain,snow, and ice by the curved overhanging bracket. The brackets mayreadily be secured to the front of any ordinary head-light, and asreadily removed.

I am also aware that a window-curtain has been provided with guides onopposite sides of the frame and slides that move on said guides, andguards of approximately circular form,that receive the edge portions ofthe curtain as the curtain is rolled and unrolled, and

I do not claim said constructions.

I claim as my invention-- 1. The combination, with the head-light, frontof the bracket, the rolljournalcd within of the curved bracket D,projecting from the the bracket and provided with the pulley H, front ofthe head-light casing and open at its the cord L, the screen on saidroll, the Weight 15 lower side, the roll K, jonrnaled within said I,having eyes J J, the ledge P, and the 5 bracket, the screen F on saidroll, the Weight guide-rods E E, extending from the ledge D I, havingeyes J J, the guide-rods E E, and to the ledge P, all substantially asset forth. the cord L, all substantially as and for the In testimonywhereof Ihavehereuntoset my purpose set forth. hand this 21st day ofNovember, 1885.

2. The combination, with the head-light, CHARLES A. FIELDS. IO of thecurved bracket D, projecting from the In presence of-- front of thehead-light casing and open at its A. C. PAUL, lower side, the ledge D,projecting from the H. N. PEcK.
